Media reports indicate that Tokyo's Narita International Airport has finalized a previously announced agreement to lower landing fees. The reduction, which will take effect Oct. 1, will lower fees 15-31 percent.

According to a report from Japan Times, the new fees will be based on noise levels from the type of aircraft an airline uses into the airport. Fees for the quietest aircraft reportedly will be 31 percent lower but even the noisiest aircraft will see a reduction of about 15 percent, According to A2A News.

Partially offset by charges for use of boarding bridges and baggage handling facilities, the reduction in fees reportedly will mean a decline in revenue of about 6-6.5 billion ($53-57 million).

Narita's move comes after intensive lobbying from the International Air Transport Association (IATA), which has been pushing the world's most expensive airports to lower their costs to airlines. Also subject to IATA criticism have been Hong Kong International Airport and Toronto's Pearson International Airport.
